摘要
本文研究了一类二阶隐式微分方程四点积分边值问题解的存在唯一性,利用压缩映像原理获得到了解的存在性结果。
In this paper, the existence and uniqueness of solution for the four-point integral boundary valve problem of a second-order implicit differential equation is discussed. In addition, the existence result of solution is obtained with contraction mapping principle.
